To obtain optimum growth through hydroponics, nutrient solution must be
1 Poorly aerated
2 Adequately aerated
3 Depends on the plant
4 None of them
Explanation:
In hydroponics, the nutrient solution must be adequately aerated in order to obtain optimum growth, because roots respire aerobically. Thus, if proper aeration is not provided, the plant can die.

The technique of growing plants in a nutrient solution in the complete absence of soil is called
1 Plant tissue culture
2 Hydroponics
3 Plant breeding
4 Aeroponics
Explanation:
In 1860, Julius von Sachs, a prominent German botanist, demonstrated, for the first time, that plants could be grown to maturity in a defined nutrient solution in complete absence of soil. This technique of growing plants in a nutrient solution is known as hydroponics.

Julius von Sachs was a ______ botanist
1 British
2 French
3 German
4 Indian botanist.
Explanation:
In 1860, Julius von Sachs, a prominent German botanist, demonstrated, for the first time, that plants could be grown to maturity in a defined nutrient solution in complete absence of soil. In 1854, Julius von Sachs provided evidence for production of glucose when plants grow.

Soilless culture helps in knowing
1 Essentiality of an element
2 Deficiency symptoms caused by an element
3 Toxicity caused by an element
4 All of them
Explanation:
With help of hydroponics technique suitable nutrient solution for the plant growth was obtained. By this method, essential elements were identified and their deficiency symptoms discovered.
